I dont use birth contral .. and it only had 7pills..
Medroxyprogestrone should make your period come within 10 days of when you stop taking it. Areyou only taking it for 10 days and stopping? Or are you taking it more often like birth control?
The medicine is going to take a couple months to regulate your period. It doesn't just happen. Give it some time but just to be safe take a pregnancy test in the morning when its most accurate
